Abstract
Photoelectron spectra following photodetachment of the gold dicarbide anion, AuC− 2 , have been recorded using the velocity map imaging technique at several excitation wavelengths. The binding energy spectra show well-defined vibrational structure which, with the aid of computational calculations and Franck-Condon simulations, was assigned to a progression in the Au–C stretching mode, ν3. The experimental data indicate that the features in the spectrum correspond to a 2A ←3A transition, involving states which we calculate to have bond angles ∼147◦ but with a low barrier to linearity.
